Orbital decay candidates reconsidered: WASP-4 b is not decaying and Kepler-1658 b is not a planet

Joshua N. Winn, Guðmundur Stefánsson

The fate of hot Jupiters is thought to be engulfment by their host stars, the outcome of tidal orbital decay. Transit timing has revealed a few systems with apparently shrinking or…

A Cold and Super-Puffy Planet on a Prograde Orbit

Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +36

We report the discovery of TOI-4507 b, a transiting sub-Saturn with a density 0.2 g/cm on a 105-day prograde orbit around a 700 Myr old F star. The transits were detected u…

Time-resolved p-mode oscillations for subgiant HD 142091 with NEID at WIYN

Jacob K. Luhn, Paul Robertson, Samuel Halverson +22

Detections of Earth-analog planets in radial velocity observations are limited by stellar astrophysical variability occurring on a variety of timescales. Current state-of-the-art m…

A Revised Density Estimate for the Largest Known Exoplanet, HAT-P-67 b

Gavin Wang, William O. Balmer, Laurent Pueyo +7

Low-density () hot Saturns are expected to quickly ( Myr) lose their atmospheres due to stellar irradiation, explaining their rarity. HAT-P-67 b seems…

Four sub-Earth planets orbiting Barnard's Star from MAROON-X and ESPRESSO

Ritvik Basant, Rafael Luque, Jacob L. Bean +9

Barnard's Star is an old, single M dwarf star that comprises the second-closest extrasolar system. It has a long history of claimed planet detections from both radial velocities an…

Calibrating the Instrumental Drift in MAROON-X using an Ensemble Analysis

Ritvik Basant, Tanya Das, Jacob L. Bean +7

MAROON-X is a state-of-the-art extreme precision radial velocity spectrograph deployed on the 8.1-meter Gemini-N telescope on Maunakea, Hawai'i. Using a stabilized Fabry-Pérot etal…

GEMS JWST: Transmission spectroscopy of TOI-5205b reveals significant stellar contamination and a metal-poor atmosphere

Caleb I. Cañas, Jacob Lustig-Yaeger, Shang-Min Tsai +21

Recent discoveries of transiting giant exoplanets () around M dwarfs (GEMS) present an opportunity to investigate their atmospheric compositions and…
